Application filed. May 3, 1919.

the prov n of a clutch and clutch op-' erating means, designed for use on a grain separator, in lieu of the regular cylinder pulley employed on separators, with a view of enabling a single attendant while working, about the separator to expeditiously and easily stop the separator in the event of trouble. provement, the clutch may be actuated to stop the separator from the top or from any other point about the separator, and hence the -'mprovement obviates the necessity of the attendant approaching the clutch and also renders it unnecessary for the operator to run from the separator to the engine that is generally located at a considerable dis tanee from the separator.

Our improvement also contemplates so constructing the-"clutch that it does not interfere in any manner with the usual belt connection between the engine and the separator.

lVith the foregoing in mind, the invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this spe ification, in which:

Figure 1 is a view showing a separator equipped with our improvement.

2 is an enlarged elevation illustrative of the arrangement of the improvement relative to the separator.

Fig. 8 is an enlarged longitudinal and diametrical section showing the arrangement of the clutch members relative to the pulley cylinder.

Figs. l, 5 and 6 are sections hereinafter specifically referred to.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Our improvement contemplates providing Specification of Letters Patent.

the separator body 1 with a sheave 2, and

also contemplates the employment of a ca tendance on the separator. The cable may be secured in a loose manner at the said point with a view to always being within convenient reach of the operator.

From the sheave 2 the cable is carried and connected to a lever 4. for disengaging the clutch, and in "conjunction with the said lever we employ a bar 5 having beveled or ratchet teeth 6, Fig. 2. From this it follows that when the cable 3 is pulled upon to move the lever 43: toward the right in Fig.2, so as to open the clutch and stop the separator, the lever will be held by one ofthe teeth 6 and consequently there will be no liability of the separator accidentally starting while the operator is away from the same.

lit 7 is the drive shaft of the separator, and at 8 is the blower belt pulley on said shaft.

Loosely surrounding the shaft 7 is the cylinder pulley 9, designed to be connected through the medium, of a belt (not shown) with the drive shaft of a tractlon engine,

also not shown. At one end the cylinder 9 receives and is connected to a collar 10. rid cylinder 9 is provided with a taper bore 11, and at its opposite end is provided with an inwardly directed portion 12 and an annular space 13 that surrounds said inwardly directed portion.

Keyed, see Fig. 4, or otherwise fixed on the shaft 7 is a sleeve member 14 that is exteriorly of angular form and cross-section and is provided with a peripheral projection 15, opposed to the inwardly directed portion 12 of cylinder 9. It will also be observed that the sleeve member 14 is provided with a nut 16 that is opposed to one end of the cylinder 9.

Arranged and movable endwise in the taper bore of the cylinder 9 is a clutch member'l'? that is provided with a facing 18., of leather or other suitable friction-creating material. The said clutch member is provided with a bore 19 of angular form in cross-section, and of a size to snugly receive the sleeve member'll.

At are what may be properly denominated as lagging blocks, to hold leather lagging 9 on the cylinder 9. Said blocks 20 are preferably of wood, and the lagging is 7 fastened thereto.

The clutch member 17 is provided with a sleeve 21, and fixed to the said sleeve isa circumferentially grooved wheel 22, between which and a surrounding collar 28, balls or other anti-friction devices 24, are interposed as shown. The collar 23 is preferably a split collar, and is provided at diametrically opposite points with journals 25 that are disposed in the arms 26 of the lever l, fulcrumed at 27 on the separator frame.

lnterposed between the outer end of the sleeve 21 on the clutch menber 17 and the pulley 8 or any other suitable abutment on the shaft 7 is a spring 80 that is put under tension by the disengagement of the clutch member 17 from the cylinder pulley 9 anu is adapted normally to maintain the clutch member 1 7 in engagement with the pulley 9 so as to cause the said pulley to transmit, motionto the shaft 7. l l hem however, the

clutch member 17'is drawn endwise out of engagement with the cylinder pulley 9, by the attendant drawing on cable 3 and mov-' ing lever 26 toward the rightin Fig. 2, the said pulley 9 will continue to turn while the shaft 7 is at rest. hflanifcstly, that portion ofthe sleeve ll on which the cylinder portion 12 is arranged isof circular form in cross-section, as shown in Fig. 6, so as to enable the pulley 9 to turn f'eely about said sleeve portion when the clutch member 17 is disengaged from the cylinder portion so as to leavethe shaft 7 at rest. 'lVhen thecable 3 is relieved of pull, the spring 30 will thrust the member l? towardthe left in. Fl

3, when rotation of shaft 7 willbe resumed.

v t will be manifest from the foregoing that our novel clutch per se is housed within the cylinder pulley 9, and is otherwise compact and strong and therefore well adapted to withstand the rough usage to Which separator appurtenances are ordinarily subjected. t

The construction herein shown and described constitutes the best practical embodiment of our invention of which we are cognizant; but it will be apparent that in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of our invention as defined by the appended claim.

Having described our invention, what we claim and desire to. secure by Letters Patent, is

7111 a clutch construction, the combination of a shaft, a sleeve member fixed to the shaft and having a radial projection at an intermediate point of its length, and also having a portion of angular form in cross-section, a nut secured on one end of said sleeve inein oer and spaced from said projection, a cylinder pulley loosely surrounding the shaft and sleeve member and having a taper bore and an inwardly directed portion loose on the sleeve member and interposed between said projection and nut, an endwise movable e rteriorly tapered clutch member, having an angular bore receiving of the sleeve member and also having a sleeve extending outwardly from one end of the clutch member, a collar fined inthe end of the pulley and loosely and snugly surrounding said extended sleeve, a wheel fixed on said shaft, a collar loosely surrounding said sleeve, and a spring surrounding; the

shaft and interposed between the clutch member and an abutment on the shaft.

In testimony whereof we afli'x our signathe angular portion
